Chinese 100w led chip lights only 35w?

I bought some chinese 100w led chip and, i measured volts coming to led are 32v and measured amperage are 1100 mah so by calculation it is about 35w what is wrong? Maybe dude who sold me led chip sold me 50w led chip? or led driver is damaged?

    It's tempting to say that perhaps they're listed as approximately as bright as 100-W bulbs but use only 35 Watts, but that efficiency sounds more in keeping with compact-fluorescent standards.

    your measuring instruments will show correctly if the power signals waveform are SINE.

    if the power signals waveforms are not SINE ... how do you calculate them?

    Since you didn't provide any details about the LED or the driver or your power source, you'll have to ask your seller.
